Are Your Intune Firewall Rules Ready for Microsoft’s Endpoint Update Before April 30, 2025?
Microsoft is tweaking its network endpoints for Intune, and if you’re managing devices on Windows, Mac, or Android, this update might affect you. It’s not rocket science, but ignoring it could lead to headaches. Let me break it down for you.
Microsoft is changing the URLs for Intune endpoints used by Windows, macOS, and Android devices. These updates impact how devices communicate with Intune services. If your firewall settings don’t align with these changes, your devices might stop talking to Intune altogether. That’s bad news.
Your devices are humming along nicely, syncing policies, apps, and updates through Intune. Then one day—bam! Nothing works. No updates. No app installs. No policy enforcement. That’s what happens when endpoints get blocked by outdated firewall rules.
If your firewall already allows traffic from *.manage.microsoft.com, you’re golden—no action required. But if you’ve got custom proxy settings or specific firewall rules in place, you need to review and update them before April 30, 2025.
Steps to Take
Let’s keep it practical. Here’s what you need to do:
Check Existing Firewall Rules
- Open your firewall configuration tool.
- Look for rules allowing traffic to *.manage.microsoft.com.
- If these rules exist and are active—great! Skip ahead.
Review Proxy Settings
If you use a proxy server, check its configuration. Ensure it allows traffic to the updated CDN endpoints listed by Microsoft.
Update Firewall Rules (If Needed)
Add or modify rules to allow traffic from the updated URLs provided by Microsoft. Test the changes to confirm connectivity.
Verify Device Connectivity
Use test devices running Windows, macOS, and Android. Confirm they can sync policies and apps through Intune after updating rules.
Communicate With Your Team
Notify other admins or IT staff about these changes. Share a deadline (April 30) for completing updates.
Pro Tip: Avoid Last-Minute Scrambles
MVP Peter Klapwijk suggests handling this sooner rather than later. Waiting until April 29 is tempting fate—don’t do it. Set aside time this week to review your settings.
Think of this as routine maintenance—like changing the oil in your car before a long road trip. It’s not glamorous but prevents breakdowns later. Don’t wait until April 29; knock this out now and sleep easy knowing your devices will stay connected.
